Description
Technical field
The present invention relates to the linear guidance device technical field, especially a kind of linear rail with long-acting lubrication effect.
Background technique
Linear rail claims again line rail, slide rail, linear guides or linear slide rail, is used for the straight reciprocating motion occasion, has the rated load higher than linear bearing, can bear certain moment of torsion simultaneously, can be in the situation that high capacity realizes high-precision straight line motion.The effect of linear rail is to support and the guided-moving parts, does linear reciprocating motion by given direction.Decide according to pressing friction character, linear rail can be divided into the kinds such as sliding friction guide rail, rolling friction guide rail, elastic-friction guide rail, fluid friction guide rail.Now commonly used is the rolling friction guide rail, comprises track and slide block, is provided with the chain type rolling element in slide block, has the rolling tread of chain type rolling element on track, and slide block by chain type rolling element and track sliding movingly.Operating time is long, and the chain type rolling element begins wearing and tearing, and the preload that acts on the chain type rolling element begins to weaken, and causes the reduction of lathe work component movement precision.If chain type rolling physical efficiency keeps lubricating status preferably, can reduce the wearing and tearing of chain type rolling element, increase the service life.As China Patent No. 03138522.2, " feeding lubricating device ", a kind of feeding lubricating device that applies to linear rail is disclosed, have oiling agent accommodating chamber and applicator on slide member, when axis of an orbit and slide member relatively move, the oiling agent in the lubricant accommodating chamber is supplied on the rolling tread of axis of an orbit and slide member by applicator.
This class formation be with lubricant applying to the rolling tread, oiling agent causes the amounts of lubrication of being stained with on the chain type rolling element on the low side all on the rolling tread, still can not well solve the long-acting of chain type rolling element and lubricate.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the bad technical problem of prior art cathetus guide rail lubrication effect, a kind of linear rail with long-acting lubrication effect is provided, directly lubricate the chain type rolling element, reduce the use amount of lubricant grease, and realize permanently effective lubricating, reduce maintenance workload.
the technical solution adopted for the present invention to solve the technical problems is: a kind of linear rail with long-acting lubrication effect, comprise track and slide block, be provided with the chain type rolling element in described slide block, has the rolling tread that matches with the chain type rolling element on track, the two ends of described slide block are equipped with recoverable capsule, slide block and recoverable capsule form the circulation loop for chain type rolling element shuttling movement, offer accommodating chamber near the circulation loop place on described recoverable capsule, the lubricant grease supplier is installed in described accommodating chamber, described oil feeding device comprises the applicator that receives lubricant grease, described applicator contacts with the chain type rolling element.Contact with applicator when the chain type rolling element rolls, thereby lubricant grease is coated on the chain type rolling element, realize long-acting lubricated.
As preferably, described applicator is foam body, and described foam body is coated with one deck cotton.Receive lubricant grease on foam body, lubricant grease is coated on the chain type rolling element when chain type rolling element contact foam body, for extending the working life of foam body, avoid foam body to cause wearing and tearing the output chip because contacting with the chain type rolling element for a long time, affect the normal operation of slide block, and at foam body outer cladding one deck cotton, to increase the service life.
Further, for increasing the amount of lubricant grease, realize the lubricated of longer time, the volume of described accommodating chamber is greater than the volume of applicator, and the space-filling between accommodating chamber and applicator has lubricant grease.This structure can make lubricant grease be kept in space between accommodating chamber and applicator, along with the consumption of the lubricant grease in applicator, ceaselessly adds in applicator, can realize the lubricated of longer time.
Further, for ease of adding lubricant grease, offer on described recoverable capsule the passage that is connected with accommodating chamber for dripping lubricant grease, the passway of described passage is provided with the screw plug for closed channel.After the lubricant grease in accommodating chamber is finished, turn on screw plug, inject the screw plug of screwing on after lubricant grease in the passage.
The invention has the beneficial effects as follows, linear rail with long-acting lubrication effect of the present invention, simple in structure, be easy to make, set up the lubricant grease supplier in recoverable capsule, can directly lubricant grease be coated on the chain type rolling element, realize the long-acting lubricated of chain type rolling element, and can reduce the consumption of lubricant grease, reduce maintenance workload.The wearing and tearing of less chain type rolling element, the working life of prolongation linear rail.
